ZDDP Oil

Hope everybody had a Happy New year. I found this article a week ago and thought this may be useful to a number of the members here. I have not ordered any but will do so when I get my Cadillac 500 built.

"We determined that viscosity will work for just about any older car and the minimum zinc/phosphorous level is guaranteed at .125 percent. Most batches test higher, " he said

.125 percent is OK but nothing at all special. Delvac 1, Delo 400, Shaeffers 7000 are all going to be higher, for less money. Rotella is basically in that same range.

Interesting that its a 15w-40.... A common diesel weight oil, considering some of the diesel weights still have the ZDDP in them. I would guess it's just a re badged product or I would at least hope its a re badged product Some guy thats only sold 4000 gallons of the stuff probably doesn't have much money for R & D.

It's also interesting they say "We're talking about a 20w50 version, too," Another common weight oil that still has the ZDDP left in it. It very well might be great stuff, I just think I would let someone else test it out first

I had never been a fan of Valvoline just because of things I heard and saw as a kid back in the 60's and 70's and how much of that was just myth or popular opinion who really knows? However, in searching for oil with "old" levels of ZDDP on the internet that wouldn't be too hard to find for break-in on the kid's 318 I found that standard Valvoline Racing Oil still has plenty and is available in 10W-30. It is marked "NOT STREET LEGAL" on the label because of the ZDDP levels. I got mine at the local NAPA store and the price was reasonable.

Another interesting thing I have seen stated in several discussions and reports on antique vehicle sites is that the "reduced" levels of ZDDP are actually the same as they were in the 50's before they started raising them for high performance engines with stiffer valve springs and that the new formulas are still safe for vintage vehicles with stock flat tappet valvetrains. Of course you can't believe everything you read, especially on the internet, but I've read it from enough different reputable sources I'm inclined to believe it. For flat tappet cam break-in and higher spring pressures I'll still play it safe and get the old formula oils.

Please don't take my word for any of this, check it out for yourselves. I'm just throwing it out there for people to look into and make their own decisions.

Valvoline bottles the oil for NAPA. We use NAPA 20/50 non synthetic on all the break ins we do, along with a bottle of EOS or Crane break in lube.
